Annular granular corneal opacity: a rare corneal stromal dystrophy or degeneration?

[...]in one report, the rings were not observed during a ophthalmic examination 14 years previously, suggesting that they are not congenital in origin. 1 Another report of a unilateral, off-white, anterior stromal, mid-peripheral ring is of note because the patient was found to have elevated serum cholesterol. 5 However, the opacity may have been a unilateral arcus. 4 Of the six bilateral cases reported, only two describe the ring as wedge-shaped in cross section and predominantly in the posterior stroma 2 and closely resemble our case.
